After hydrogen treatment, lotus-shaped nitrogen and fluorine co-modified anatase TiO2 (NF-TiO2) with {0011 facets have been synthesized and employed as photoanode materials in dye sensitized solar cells (DSSCs). In comparison with non-modified TiO2 based DSSC, we obtain a 40% enhancement of photocurrent and a 38% increase of photoelectric conversion efficiency. UV-visible absorption spectroscopy (UV-vis) and Mott-Schottky plots combined with valence band analysis are used to characterize the electronic structure variation and study the synergistic effect of hydrogen treatment. The result shows an enhanced light absorbing ability, is a positively shifted flat band potential and an increased donor density. These improvements can be mainly ascribed to the appropriate electronic structure and the effective light-scattering centers. This work provides systematic and comprehensive research on the application of hydrogenation and 001) facets dominated nitrogen and fluorine co-modified TiO2 in DSSC, and the hydrogenation treatment can lead to improved charge transport and recombination, enhanced light absorbing ability as well as elevated donor density of semiconductor. With these merits, (001) facets dominated HNF-TiO2 nanopowders in this work may find its way in enormous energy and photoelectric fields. (C) 2017 Elsevier B.V. All rights reserved.
